Santa Monica's legal case to control future use of its airport land is heavy with language about quitclaim deeds and statutes of limitations. But the heart of its case against the Federal Aviation Administration is this: the city shouldn't have to run an airport forever.

The FAA responded asking the federal court to dismiss the city's complaint.

The city signed a deed in 1948 to regain airport land that had been leased to the federal government during the war. The FAA argues the deed included a key condition — that the city keep using the property for aviation.

The FAA also argued that the city had asked — and been granted — permission to remove parcels from the aviation use condition three times in the past several decades. That, the federal agency says, indicates the city acknowledged it needed federal permission to deviate from the deed.

Santa Monica says it is unconstitutional for the FAA to require the city to use the land as an airport forever.

The FAA's dismissal motion and the city's response will be heard Feb. 10 in U.S. District Court in Los Angeles.
